The Star Trek: The Next Generation Technical Manual (p. 117) provides more detailed information on the class-5 medium range reconnaissance probe. It is powered by a small matter-antimatter engine, providing power for extended duration sublight and a limited duration warp travel at a maximum of warp factor 2 speed. It has a range of 43 billion kilometers and is designed with planetary atmosphere entry and soft landing capability. The probe has low observability hull materials and coating. Its sensors are designed for extended passive data-gathering and recording. The probe is designed to function as a full autonomous craft in executing its mission and returning home. Telemetry includes 6,320 channels at 2.5 megawatts. The probe can also be modified for tactical applications with the addition of a customized sensor countermeasure package.
